GAS-LIGHTING- FIXTURE.

Specification of Letters Patent.

Patented Oct. 29, 1918.

Application filed March 17, 1917. Serial No. 155,479.

To all whom t may Concern.'

Be it known that I, PAUL A, Rose, a citizen of the United States, residing at Cranford, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Gas-Lighting Fixtures, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in shade holders for gas burners and is particularly adapted for use with acetylene burners where it is desired to use an inverted globe. In theburir` ing of acetylene it has been found imprac-v ticable to use the well known type of inverted burner since the heat of combustion so heats up the conducting tube that the acetylene disassociates into various undesirable compounds.

In the present invention I provide a holder adapted for use in connection with the well known upright burner, which holder is adapted to receive and support an inverted globe. The parts are so arranged that the holder can be placed in position without disassembling or detaching the burner tube and when so assembled the burner tube is disposed to one side of the burner whereby the heat of combustion does not disassociate the acetylene in the tube.

Further ob]l ects of my invention reside in the provision of a device which is inexpensive to manufacture and in which the assembly of the parts is siinpliiied.

In the drawings Figure 1 is a view in cross section showing the shade or globe holder in position on the burner tube.

Fig. 2 is a plan view, omitting the globe and burner.

Fig. 3 is a section showing modified method of attaching the bracket supporting boss to the burner tube.

Figs. 4 and 5 are sections on lines 4.-1 and 5 5 respectively, showing two methods of fastening the bracket or spider to the shade holder.

In more detail, 10 is the burner tube. This tube, which is threaded at its upper end for connection in the usual way with a source of gas, not shown, extends downward and is curved at its lower end to space the burner 10", screwed upon nipple 11, laterally away from the tube. At a suitable height above the lower end 0f the tube there is a ring 12 having a radial flange 13, the ring and its fiange being in one piece, punched from sheet metal and secured to the burner tube by soldering, or by crimping as indicated at 14 in 3.

The shade or globe holder 15 is of sheet metal and carries the usual globe-holding set screws 16. To support the shade holder in place I provide a bracket or spider 17 which comprises a piece of bent wire or other stock bent to form 'a Y-shaped portion or bight 1S, the en d portions 19, 20, flaring as shown. 'Ihe latter, and the outermost end of the Y-portion are attached to the shade holder either by screws 21, as in Fig. 5, or by extruding a part of the metal of the bracket and riveting this portion over as shown at 22 in Fig. 4.

It will be observed that the crotch or Y-shaped portion of the bracket is eccentric to the annular globeholder 15. lVhen it is desired to put the holder and globe in place upon the burner tube the holder is passed up over the end of the burner tube, the burner being already in place. As shown in Fig. 9. there is ample room to pass the burner tube and burner between the bracket arms 19, 20. The holder is then displaced laterallyuntil the pipe 10 abuts against the crotch in the Y-portion of the bracket, the latter resting upon ange 13. Screws 23 are then passed through holes in the bracket and screwed into tapped holes in the said flange 13 of ring 12. The globe (indicated in dotted lines at 211) is then inserted and secured in the ring ,or holder 15, and the burner is ready for use. To remove the globe and globe-holder from the burner tube the operations just described are reversed.

lVhile not essential it is desirable to have the crotch 0r Y-portion of the bracket spaced far enough laterally from the center' of the globe-holder 15 to bring the center of the latter substantially into vertical alinement with the burner, as in Fig. 1. The angle between the arms 19, 20, is ratherwide, so that neither will be directly over the burner. Preferably they are spaced as far as possible from the plane of the burner and burner tube, to minimize heating of the arms and consequent conduction of heat to the burner tube.

It is to be understood that the invention is not limited to the specific construction herein specifically described but can be embodied in other forms Without departure from its s pirit.

I claim:

l. The combination with a depending burner tube having a laterally displaced burner at its lower end, of a globe-holder above the burner, and a bracket having a crotch embracing and Supported by the burner tube and having` a plurality of arms attached to the globe-holder to support the same, the crotch 'being eccentric to the globeholder whereby the center of the latter is held in substantially vertical alinement with the burner.

2. A globe-holder adapted for attachment to a depending burner tube having a laterally displaced burner, comprising a globeholding frame; a bracket within the frame and having branch portions secured thereto, with a crotch portion adapted to embrace the burner tube, the crotch portion being eccentric to the Said frame, to permit passing ci the burner tube and attachments between the frame and the bracket; and means for securing the bracket to the tube when the latter is in the aforesaid crotch portion.

3. A lighting iXture comprising a depending burner tube having an oilset lower end carrying a burner, a bracket-supporting member en the said tube, a bracket independent ef the burner tube and adapted for attachment to said member, a globe-holder attached to the bracket, said bracket being constructed to permit passing 0i' the burner and burner tube between the globe-holder and the bracket and to support said holder centrally over the burner, and means for attaching said bracket to said member.

4. The combination with a depending burner tube having a laterally displaced burner at its lower end, of a globe holder above the burner, and a bracket having a crotch embracing and supported by the burner tube, said bracket having` flattened portions to receive screws for securing said bracket to the tube when the latter is in the aforesaid crotch portion.

5. A globe holder adapted for attachment to a depending burner tube having a laterally displaced burner, comprising a globe holding frame, a bracket within the frame and formed of one piece of wire bent to Y-shape with a widened portion in the stem of the Y to accommodate the burner tube, and means for securing the bracket to the tube when the latter is in the aforesaid position.

In testimony whereof I aX my signature.
